| 摘要 |
<p>The invention relates to a polymer of core-shell structure containing a core having at least one elastomeric polymer, with a glass transition temperature of less than 25° C., and a shell having at least one polymer, with a glass transition temperature of greater than 25° C., where at least one of the polymers includes (meth)acrylic acid ester monomers containing organic carbon derived from biomass. The present invention also relates to a process for preparing the core-shell polymers and to their use as impact additives, and to a composition containing them.</p> |
